Product Summary

The s7136-10 is a light modulation photo IC developed for optical synchronous detection under disturbance background light. A photodiode, preamplifier, comparator, oscillator, LED drive and signal processing circuit, etc are all integrated on a monolithic photo IC chip. Optical synchronous type photoreflectors and photointerrupters, which less suceptible to disturbance background light, can be easily configured by just connecting and external LED to this photo IC. Our unique circuit design achieves an allowable background light level of 10000 lx typ and a minumum detection level of 0.2 uW/mm2 type. The applications of the s7136-10 are paper detection in office machine (copiers, fax machines, etc.) and optical switch.
